Description

Technical Field

[0001] This invention relates to the technical field of wireless headphones, and in particular to a headphone charging case and wireless headphones. Background Technology

[0002] The earphone charging case is used for storing and charging earphones. In order to reduce the difficulty of opening the earphone charging case, i.e. to make it easier to open the earphone charging case, the traditional technology is to install magnets on both the top and bottom covers, and use the repulsive force of the magnets to open the case, for example, the invention patent with publication number CN113243115B.

[0003] Because irregularly shaped magnets are expensive, multiple round magnets are typically installed inside the top and bottom covers to reduce overall magnet costs. However, installing each magnet requires applying adhesive to secure it in place, leading to multiple adhesive applications during the assembly of the earphone charging case, resulting in low assembly efficiency. Furthermore, the compact structure of the earphone charging case and the limited space available for magnet installation in the top and bottom covers make adhesive application difficult, resulting in low yield and ultimately a low overall pass rate for the earphone charging case. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an earphone charging case and wireless earphones that improve the assembly efficiency and yield of the earphone charging case.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] An earphone charging case includes a top cover and a case body. The top cover has a rotating portion at its periphery, which is rotatably connected to the case body so that the top cover can be opened and closed to close onto the case body. The case body forms a movable cavity. The earphone charging case further includes an opening mechanism, which includes:

[0007] A connector is located inside the movable cavity. The first end of the rotating part is located inside the movable cavity and is rotatably connected to the first end of the connector. The second end of the rotating part is rotatably connected to the periphery of the box body.

[0009] An elastic assisting component is located inside the movable cavity, and the elastic assisting component abuts against the second end of the sliding lifting component and the inner wall of the movable cavity respectively. The elastic assisting component is in a compressed state after the upper cover is closed, and the elastic assisting component extends when the upper cover is opened to push the sliding lifting component to move upward, thereby causing the connecting component and the upper cover to rotate, and thus the elastic assisting component is used to push the upper cover to open.

[0010] In one embodiment, the movable cavity is formed on the outside of the box body, the movable cavity extends along the height direction of the box body, and the sliding direction of the sliding lifting member is parallel to the extension direction of the movable cavity.

[0011] In one embodiment, the extending direction of the connector forms an angle with the sliding direction of the sliding lifting member when the upper cover is closed, and the first end of the connector is closer to the opening of the movable cavity than the second end of the connector when the upper cover is closed.

[0012] In one embodiment, a clearance groove is formed on the side of the connector adjacent to the opening of the movable cavity.

[0013] In one embodiment, the opening mechanism further includes a guide post located within the movable cavity and fixedly connected to the box body, and the sliding lifting component is slidably connected to the guide post.

[0014] In one embodiment, the elastic support element is sleeved on the guide post.

[0015] In one embodiment, the elastic support element is a spring or a sheet spring; and / or,

[0016] The box body has a limiting part protruding from the movable cavity, and the sliding lifting member forms a limiting hole. The limiting part is located in the limiting hole, so that the limiting part is used to limit the sliding stroke of the sliding lifting member.

[0017] In one embodiment, the box body further forms a first receiving groove and a sliding through hole that are connected to each other, wherein the sliding through hole extends to the outer side of the box body, and the box body forms a clearance lifting hole that is connected to the movable cavity and the sliding through hole respectively.

[0018] The earphone charging case also includes a lifting compartment, which is slidably connected to the sliding through hole. The sliding lifting component has a protruding ear compartment connecting part, which passes through the clearance lifting hole and is connected to the lifting compartment, so that the sliding lifting component can also drive the lifting compartment to move up and down. The lifting compartment forms a second receiving groove, and the first receiving groove and the second receiving groove are connected in sequence to form an earphone receiving cavity.

[0019] In one embodiment, the housing is formed with a communicating recessed insertion hole and a limiting groove, wherein the recessed insertion hole is communicating with the sliding through hole;

[0020] The earphone charging case also includes an auxiliary mounting component, which includes a connected insert rod and a pre-installed housing part. The insert rod is rotatably embedded in the limiting groove, and the pre-installed housing part passes through the clearance insertion hole and is rotatably connected to the lifting housing.

[0034] This application provides an earphone charging case, including a top cover and a case body. The top cover has a rotating portion at its periphery, which is rotatably connected to the case body, allowing the top cover to be opened and closed onto the case body. The case body forms a movable cavity. The earphone charging case also includes an opening mechanism, which includes a connector, a sliding lifting member, and an elastic assist member. The connector is located within the movable cavity. The first end of the rotating portion is located within the movable cavity and rotatably connected to the first end of the connector. The second end of the rotating portion is rotatably connected to the periphery of the case body. The sliding lifting member is slidably connected up and down within the movable cavity. The second end of the connector is rotatably connected to the first end of the sliding lifting member. The elastic assist member is located within the movable cavity and abuts against the second end of the sliding lifting member and the inner wall of the movable cavity. The elastic assist member is in a compressed state after the top cover is closed.

[0035] The aforementioned earphone charging case and wireless earphones feature an elastic mechanism that automatically opens the lid when the user opens it to a certain extent.

Since there's no need to use magnets to enhance opening convenience, there's no need to apply adhesive to magnets during the assembly process, improving assembly efficiency and avoiding the low yield issues associated with adhesive application, thereby increasing the overall pass rate of the earphone charging case.

[0036] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0037] like Figures 1 to 4 As shown, one embodiment of the earphone 200 includes an earphone charging case 100 and earphones 200, with the earphones 200 housed within the earphone charging case 100. In one embodiment, the earphone charging case 100 includes a top cover 110 and a case body 120. The top cover 110 has a rotating portion 111 at its periphery, and the rotating portion 111 is rotatably connected to the case body 120 so that the top cover 110 can be opened and closed to cover the case body 120.

[0038] like Figures 2 to 4 As shown, the housing 120 further includes a movable cavity 121, and the earphone charging case 100 also includes an opening mechanism 130. The opening mechanism 130 includes a connector 131, a sliding lifting member 132, and an elastic assist member 133. The connector 131 is located within the movable cavity 121, and the first end of the rotating part 111 is located within the movable cavity 121 and rotatably connected to the first end of the connector 131. The second end of the rotating part 111 is rotatably connected to the periphery of the housing 120. The sliding lifting member 132 is slidably connected up and down within the movable cavity 121, and the second end of the connector 131 is rotatably connected to the first end of the sliding lifting member 132. The elastic assist member 133 is located in the movable cavity 121, and the elastic assist member 133 abuts against the second end of the sliding lifting member 132 and the inner wall of the movable cavity 121 respectively. The elastic assist member 133 is in a compressed state after the upper cover 110 is closed. The elastic assist member 133 extends when the upper cover 110 is opened to push the sliding lifting member 132 to move upward, thereby causing the connecting member 131 and the upper cover 110 to rotate, thereby enabling the elastic assist member 133 to push the upper cover 110 to open.

[0039] like Figure 4 and Figure 5As shown, in this embodiment, when the upper cover 110 rotates in the opening direction, the rotating part 111 of the upper cover 110 drives the connecting member 131 to rotate, so that the connecting member 131 drives the sliding lifting member 132 to slide upward a certain distance after the opening is completed; when the upper cover 110 rotates in the closing direction, the rotating part 111 of the upper cover 110 drives the connecting member 131 to rotate, and at this time the rotation direction of the connecting member 131 is opposite to the rotation direction when the opening is completed, so that the connecting member 131 drives the sliding lifting member 132 to slide downward a certain distance after the closing is completed.

[0040] like Figure 4 and Figure 5 As shown, further, when the top cover 110 is closed, the elastic assist member 133 abuts against the inner wall of the movable cavity 121 and the end of the sliding lifting member 132 away from the connecting member 131, so that the elastic assist member 133 is in a compressed state. When the user opens the top cover 110 to a certain angle, for example, after the top cover 110 is rotated 30° in the opening direction, the elastic assist member 133 will extend and push the sliding lifting member 132 to slide upward, so that the sliding lifting member 132 can slide upward without user operation, thereby allowing the connecting member 131 to rotate without user operation, and thus allowing the top cover 110 to rotate in the opening direction without user operation, that is, the top cover 110 can be opened automatically without user operation. Thus, when the user opens the top cover 110 to a certain extent, the elastic assist component 133 will drive the top cover 110 to open automatically. That is, the top cover 110 can open automatically when the user releases the pressure, or it will automatically open after being manually opened to a certain angle, thus improving the ease of opening. Since there is no need to install magnets to improve the ease of opening, there is no need to apply glue to magnets during the assembly process of the earphone charging case 100, improving the assembly efficiency of the earphone charging case 100. At the same time, it avoids the low yield problem caused by glue application, thus improving the pass rate of the earphone charging case 100.

[0041] like Figure 4 As shown, in one embodiment, the movable cavity 121 is formed on the outer side of the box body 120, and the movable cavity 121 extends along the height direction of the box body 120. The sliding direction of the sliding lifting member 132 is parallel to the extension direction of the movable cavity 121, so as to improve the lifting efficiency of the sliding lifting member 132. In this embodiment, since the movable cavity 121 is formed on the outer side of the box body 120, the efficiency of the lid opening mechanism 130 being installed in the movable cavity 121 is improved.

[0042] like Figure 4As shown, in one embodiment, the extending direction of the connector 131 forms an angle with the sliding direction of the sliding lifting member 132 when the upper cover 110 is closed, and the first end of the connector 131 is closer to the opening of the movable cavity 121 than the second end of the connector 131 when the upper cover 110 is closed. In this embodiment, when the upper cover 110 is closed, the connector 131 is tilted, and there is an angle between the sliding direction of the connector 131 and the sliding lifting member 132. The first end of the connector 131 is adjacent to the opening of the movable cavity 121, and the second end of the connector 131 is away from the opening of the movable cavity 121, so that the first end of the connector 131 is closer to the opening of the movable cavity 121 than the second end of the connector 131 when the upper cover 110 is closed, thereby realizing the linkage of the upper cover 110, the connector 131, and the sliding lifting member 132.

[0043] like Figure 4 and Figure 5 As shown, further, when the upper cover 110 rotates in the opening direction, the connecting member 131 rotates under the drive of the rotating part 111 of the upper cover 110, causing one end of the connecting member 131 adjacent to the rotating part 111 to gradually extend into the movable cavity 121, so that both the connecting member 131 and the sliding lifting member 132 move downward. When the end of the connecting member 131 adjacent to the rotating part 111 is further away from the opening of the movable cavity 121 than the other end of the connecting member 131, both the connecting member 131 and the sliding lifting member 132 move upward. When the upper cover 110 is opened to its maximum angle, i.e., when the opening is completed, both the connecting member 131 and the sliding lifting member 132 stop moving upward. During the opening process, the upward distance of the connecting member 131 is greater than the downward distance of the connecting member 131, and the upward distance of the sliding lifting member 132 is greater than the downward distance of the sliding lifting member 132.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, a recessed groove 1311 is formed on the side of the connector 131 adjacent to the opening of the movable cavity 121 to prevent the connector 131 from obstructing the opening of the cover 110.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, the opening mechanism 130 further includes a guide post 134, which is located in the movable cavity 121 and fixedly connected to the box body 120. The sliding lifting member 132 is slidably connected to the guide post 134 to improve the smoothness of the sliding of the sliding lifting member 132.

[0046] like Figure 3 As shown, in one embodiment, the elastic assist member 133 is sleeved on the guide post 134 to improve the positional stability of the elastic assist member 133, thereby ensuring that the elastic assist member 133 functions.

[0047] like Figure 3 As shown, in one embodiment, the elastic assist 133 is a spring or sheet to make the elastic assist 133 elastic.

[0048] like Figure 3 As shown, in one embodiment, the housing 120 has a limiting part 120a protruding from the movable cavity 121, and the sliding lifting member 132 forms a limiting hole 1321. The limiting part 120a is located in the limiting hole 1321, so that the limiting part 120a is used to limit the sliding stroke of the sliding lifting member 132.

[0049] like Figure 4 and Figure 5 As shown, in one embodiment, the housing 120 further forms a first receiving groove 122 and a sliding through hole 123 that are connected to each other. The sliding through hole 123 extends to the outer side of the housing 120. The housing 120 forms a clearance lifting hole 124, which is connected to the movable cavity 121 and the sliding through hole 123 respectively. Further, the earphone charging case 100 also includes a lifting compartment 140, which is slidably connected to the sliding through hole 123. A sliding lifting member 132 protrudes and is provided with an ear compartment connecting part 1321. The ear compartment connecting part 1321 passes through the clearance lifting hole 124 and is connected to the lifting compartment 140, so that the sliding lifting member 132 is also used to drive the lifting compartment 140 to rise and fall. The lifting compartment 140 forms a second receiving groove 141. The first receiving groove 122 and the second receiving groove 141 are connected in sequence to form an earphone receiving cavity, which is used to receive the earphone 200.

[0050] like Figure 4 As shown, in this embodiment, since the lifting chamber 140 is fixedly connected to the ear compartment connection portion 1321 of the sliding lifting member 132, the lifting chamber 140 and the sliding lifting member 132 move synchronously, that is, the lifting chamber 140 moves up and down following the sliding lifting member 132. When the cover is opened, the lifting chamber 140 also moves up due to the upward movement of the sliding lifting member 132, thereby causing the lifting chamber 140 to move the earphone 200 away from the first receiving slot 122, increasing the extension length of the earphone 200 and improving the convenience of taking out the earphone 200.

[0051] like Figure 2 As shown, in one embodiment, the housing 120 is formed with a communicating recessed insertion hole 125 and a limiting groove 126, wherein the recessed insertion hole 125 is connected to the sliding through hole 123.

[0052] like Figure 5 and Figure 6As shown, the earphone charging case 100 further includes an auxiliary mounting component 150. The auxiliary mounting component 150 includes a connected inserting rod 151 and a pre-installed housing part 152. The inserting rod 151 is rotatably embedded in the limiting groove 126, and the pre-installed housing part 152 passes through the clearance insertion hole 125 and is rotatably connected to the lifting housing 140. In this embodiment, when assembling the lifting housing 140, the lifting housing 140 is pushed into the sliding through hole 123 from the bottom of the box body 120. Then, the pre-installed housing part 152 of the auxiliary mounting component 150 is aligned with the clearance insertion hole 125, and then the auxiliary mounting component 150 is pushed into the box body 120 so that the pre-installed housing part 152 is connected to the lifting housing 140, and the inserting rod 151 is embedded in the limiting groove 126, thereby initially installing the lifting housing 140 into the box body 120.

[0053] Furthermore, after the initial installation of the lifting chamber 140 is completed, the sliding lifting component 132 is installed in the movable cavity 121 so that the ear compartment connecting part 1321 passes through the clearance lifting hole 124 and connects with the lifting chamber 140, thereby completing the installation of the lifting chamber 140 and allowing the lifting chamber 140 and the sliding lifting component 132 to move up and down synchronously. When the sliding lifting component 132 drives the lifting chamber 140 to rise and fall, the auxiliary mounting component 150 rotates relative to the lifting chamber 140, and the embedded rod 151 rotates within the limiting groove 126. In this way, before the lifting chamber 140 is connected to the sliding lifting component 132, the lifting chamber 140 is pre-fixed by the auxiliary mounting component 150, which improves the ease of alignment between the sliding lifting component 132 and the lifting chamber 140, thereby improving the efficiency of the connection between the sliding lifting component 132 and the lifting chamber 140, and thus improving the assembly efficiency of the earphone charging case 100.

[0054] like Figure 2 and Figure 6 As shown, in one embodiment, there are two recessed insertion holes 125, which are respectively connected to both ends of the limiting groove 126. The lifting chamber 140 forms two rotating grooves 142, and there are two pre-installed chamber parts 152. The two pre-installed chamber parts 152 are respectively fixedly connected to both ends of the embedding rod 151. The two pre-installed chamber parts 152 and the embedding rod 151 are integrally formed to improve the assembly efficiency of the earphone charging case 100. The two pre-installed chamber parts 152 are respectively embedded in the two rotating grooves 142 and rotatably connected to the lifting chamber 140. In this embodiment, by pushing the auxiliary mounting component 150, the two pre-installed chamber parts 152 can pass through the two recessed insertion holes 125 and be embedded in the two rotating grooves 142 respectively. At the same time, the embedding rod 151 can also be embedded in the limiting groove 126, which improves the installation efficiency of the auxiliary mounting component 150 and thus improves the assembly efficiency of the earphone charging case 100.

[0055] like Figure 6As shown, in one embodiment, the lifting chamber 140 has connecting blocks 140a protruding on both opposite sides, and two rotating grooves 142 respectively form two connecting blocks 140a, so that the two chamber pre-installation parts 152 are rotatably connected to the two connecting blocks 140a.

[0056] like Figure 6 As shown, the connecting block 140a adjacent to the sliding lifting member 132 further forms a connecting hole 142. The ear chamber connecting part 1321 of the sliding lifting member 132 is located in the connecting hole 142 and is rotatably connected to the connecting block 140a so that the sliding lifting member 132 is connected to the lifting chamber 140, thereby making the sliding lifting member 132 and the lifting chamber 140 move up and down synchronously.

[0057] like Figure 2 As shown, in one embodiment, the housing 120 has locking blocks 120b formed on two opposite sidewalls of the limiting groove 126, and the insert rod 151 is located within the limiting groove 126 and rotates against the locking blocks 120b. In this embodiment, since the insert rod 151 contacts the locking blocks 120b within the limiting groove 126, the contact area between the insert rod 151 and the housing 120 is reduced, the rotational resistance of the insert rod 151 is reduced, and thus the smoothness of the up-and-down movement of the lifting chamber 140 and the sliding lifting component 132 is improved.

[0058] like Figure 3 As shown, in one embodiment, there are three guide posts 134. All three guide posts 134 are located in the movable cavity 121 and are fixedly connected to the box body 120. The sliding lifting member 132 is respectively sleeved on the three guide posts 134 so that the three guide posts 134 guide the up and down movement of the sliding lifting member 132, while restricting the rotation of the sliding lifting member 132, improving the sliding stability of the sliding lifting member 132, and thus improving the smoothness of opening the top cover 110.

[0059] like Figure 1 As shown, in one embodiment, the earphone charging case 100 further includes a decorative cover 160, which is fitted onto the upper cover 110 to prevent the structure on the surface of the upper cover 110 from being exposed, thereby improving the surface flatness of the earphone charging case 100 and thus enhancing its aesthetics. The earphone charging case 100 also includes a decorative box 170, which is fitted onto the case body 120 to prevent the structure on the surface of the case body 120 from being exposed, further improving the surface flatness of the earphone charging case 100 and thus enhancing its aesthetics.

[0060] Compared with the prior art, the present invention has at least the following advantages:

[0061] When the user opens the top cover 110 to a certain extent, the elastic assist component will drive the top cover 110 to open automatically. That is, the top cover 110 opens automatically when the user releases the pressure, improving ease of opening. Since there is no need to install magnets to improve ease of opening, there is no need to apply glue to magnets during the assembly process of the earphone charging case 100. This improves the assembly efficiency of the earphone charging case 100 and avoids the low yield problem caused by glue application, thus increasing the pass rate of the earphone charging case 100.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
